Hi, I have 03 Raptor and was thinking about boring it out. What mods would I absolutly have to do ? Because I look stuff up on the internet and it shows $3,000 worth of parts, but i know it cant be that much just to bore out the engine....is it? Thanks for the help.

To do a 727 you need to take the whole engine apart to machine the case. You also can't just bore the cyl., it needs a different sleeve. The prices you've seen probably include other things like replacing the rod (since it's apart) or porting, gaskets and so on.

You can buy a kit on ebay buy it now for $329.....It includes everything you need minus an aftermarket rod which you can get by without if you choose. You will have to split the cases to have them machined. If a person were interested, I have a set of cases that are already machined for a 727 kit. You can email me @ jtk23@insightbb.com ....I bought a similar kit on Ebay for about the same price.
